When I say "lower class", I don't mean people of little means, I mean the type of folks who walk around wearing stained wife beaters, while the women sit on the porch in a housecoat and rollers, cursing at the world. Many of the folks I went to school with as a child would've been considered "middle class" but were VERY low class in their attitudes toward others.
I can't speak for Clemenza but I have a feeling he is refering to the rather ignorant people who many of us had in our peer circle who plain did not LIKE Mexicans,calling them spics and wetbacks.
This was WAY before the illegal invasion.The debate on this issue should never be racialized but one needs to be honest and realstic and admit that many American whites-and many Mexicans here AND in Mexico-are trying to stir up the racial doo doo.
